For nature lovers, scientists, even general use, close-
up
photography provides the means to see the world
in
all
its smallest details.
The
following are available
for close-up work at a shorter distance than that of
Hie

on
the lens:

PB-6-Use
the
aperture
control lever of the PB-6 for stop-down
measurement
as
follows:
on
A,
release the shutter
button after turning the PB-6's aperture
control
lever;
on
manual, turn the aperture control of the
PB-6 and turn either the flstop or shutter
dial until
only
the steady
LED
begins to light, indicating
correct exposure for
manual mode. Note that P
(Program) mode
is
unusable. Shooting magnifi-
cation
is
successively changeable by the expan-
sion and contraction of the
bellows.
Any combination of Nos.
1,
2,
and 3
is
possible.

(4) Micro-Nikkor 55mm fl2.8, 105mm
f/2.8
and
200mm fl4
(IF)-When
using AI-type Micro-Nikkor
lenses at a shooting magnification range from 1/2
to 1/1, use the Auto
Ring
PK-13
or Teleconverter
TC-201
(in the case of the TC-201, usable from
infinity
to
1/1
magnification) with the 55mm f/2.8;
use the
PN-11
with the 105mm f/2.8.
In
the case
of the
200mm f/4 (IF), the Teleconverter TC-301
is
recommended for photos with a wide magnification
range from infinity to
1/1. Because both the auto
rings and
teleconverters have automatic aperture
coupling devices, they enable automatic exposure
control when combined with Micro-Nikkor lenses.
For close-up photography with these accessories,
it
is
recommended to shoot at A or manual modes since
depth of
field
is
generally shallow and you must stop
your aperture down
as
much
as
possible to get the
greatest area of
clear focus.
In
focusing, it
is
essen-
tial to focus
on
the matte field.
To
measure the exact
distance between the subject and the
film plane, use
the
film plane indicator.
